NotCollege - I did not see the RSCOM defined in your linked thread.
Thanks NotCollege.I am by means no expert but was intrigued by the question and did some research. It appears RSCOM stands for reserve components nomination.(source-http://www.serviceacademyforums.com/index.php?threads/rscom.37215/) According to West Point's website this is how you receive this nomination. I hope this helps to clarify
- Regular Army and Reserve Components (Army, Army Reserve, and Army National Guard)
To request a nomination under this category, submit your commander's endorsement, which is included in your application. Please provide your commander with the following Commander's Guidance that can be used during his interview with you. Soldiers who are not offered an appointment to West Point are automatically considered for enrollment in the United States Military Academy Preparatory School (USMAPS).
